Lisa becomes Bart's Little League coach in order to expand her extracurricular activities, but Bart comes to hate it when Lisa begins sucking the fun out of baseball.

!! Tropes:

* BoringYetPractical: Lisa uses math to lead the team to victory. Bart would rather be AwesomeButImpractical.
* BaitAndSwitchComment: A commentator said that, speaking of Homer, Lisa's father's name was... not in the list.
* CallBack: Marge recalls Mike Scioscia's radiation poisoning from ''[[Recap/TheSimpsonsS3E17HomerAtTheBat Homer at the Bat]]''.
* GenderBlenderName: When Bart accused Lisa of not understanding baseball, she brought up legendary baseball names of what she believed to be women (Terry Francona, Connie Mack). Nelson tells her those are men.
* KnowNothingKnowItAll: The aforementioned incident of Lisa claiming that women could coach baseball, using Terry Francona and Connie Mack as examples.
